Zeolite

Mathematicians describe the most beautiful and beguiling forms and surfaces they know

Low-carbon concrete is now in use on in many construction projects—and it's cheap enough that it's poised to rival the polluting version.

Parents of newborns are reporting symptoms including diarrhea, twitching, and "complete toddler meltdowns" after giving them Pure Body Extra detox treatment.

Who'd have thought that the solution to some of our energy problems would be something as simple as ice cubes?

UC Berkeley researchers have designed an extreme-weather proven, hand-held device that can extract and convert water molecules from the air into drinkable water using only ambient sunlight as its energy source, a study published in Nature Water today shows. This atmospheric water harvester used an ultra-porous material known as a metal-organic framework (MOF) to extract water repeatedly in the hottest and driest…

Researchers have reported a strategy to disentangle the activity-selectivity tradeoff for direct conversion of syngas, a mixture of carbon monoxide and hydrogen, into desirable ethylene, propylene, and butylene. These hydrocarbons are known as light olefins and are the most-used building blocks for plastics.

The Prospering Backyards project brings together scientists, artists, activists and community members to tackle an environmental disaster that has quietly festered for decades.

When oil contaminates water, it creates a film that reduces oxygen levels and introduces toxic substances. This can lead to the death of aquatic plants and animals, contaminate soil, and ultimately threaten human health.

Methanol-to-olefins (MTO) conversion, one of the most important reactions in C1 chemistry, has proven to be the most successful non-petrochemical industrialized routes for producing light olefins. Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has been dedicated to the R&D of the MTO reaction for the past four decades.

When it comes to soap, stronger isn't necessarily better.

Methanol, produced from carbon dioxide in the air, can be used to make carbon neutral fuels. But to do this, the mechanism by which methanol is turned into liquid hydrocarbons must be better understood so that the catalytic process can be optimized. Now, using sophisticated analytical techniques, researchers from ETH Zürich and Paul Scherrer Institute have gained unprecedented insight into this complex mechanism.

A research team led by Prof. Pan Xiulian and Prof. Bao Xinhe from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences realized the direct synthesis of isoparaffin-rich gasoline from syngas using ZnAlOx-SAPO-11 oxide-zeolite (OXZEO) catalysts.

Zeolites are one of the shape-selective catalysts. The characteristics of zeolites, which come from the structural confinement on the molecular dimensions, are crucial for shape-selective catalysis.

Wind turbine blades made from glass fiber-reinforced polymer (GFRP) laminate composites can serve for up to 25 years. After that, they end up in landfills which has become a real challenge for the renewable energy industry. Researchers have proposed a method for wind turbine blades' recycling. Using pyrolysis, they broke the composite materials into their constituent parts. According to scientists, the extracted…

Zeolites, which are crystalline porous materials, are very widely used in the production of chemicals, fuels, materials, and other products.  So far, zeolites have been made as 3D or 2D materials. This has changed with the recent discovery of crystalline zeolites in a nanotubular (1D) shape, by researchers at the Georgia Institute of Technology, Stockholm University, and Penn State University. The findings were…

In the UK, a simple, low-cost method of directly converting natural gas into useful chemicals and fuels, using the precious metal gold as a key ingredient, has been proposed by researchers at Cardiff University in collaboration with researchers in Lehigh University, U.S. and the National Centre for Magnetic Resonance in Wuhan, China.  In a study […]

In a two-step process, a new catalyst can convert methane into polymers at ordinary temperature and pressure.

A California company says it has developed a novel way of making concrete that doesn't contribute to global warming

Montana State University researcher James Crawford recently published a collaborative paper with the National Renewable Energy Laboratory that marks a step forward in their quest for what he calls a "holy grail" of chemistry: converting the greenhouse gas carbon dioxide into chemical building blocks that could be used to create myriad other materials.
